This article has compiled two functional files for PHP Chinese character pinyin conversion and Gregorian and lunar calendar conversion, which are very practical. For example, when we search the address book, we can search by the pinyin initials of the contact's name, we can navigate large amounts of data by the initials, and we can do website optimization by converting pinyin. Public lunar calendar conversion is generally used in calendar scheduling projects to facilitate lunar calendar festival reminders, etc.
1. Convert Chinese characters to Pinyin with PHP
The Pinyin.class.php class file can convert most Chinese characters into Chinese Pinyin. Of course, there are some rare characters that cannot be converted. If you want to convert all Chinese characters into Pinyin, you may need to use another Chinese character library to achieve it. Use this Class files can basically meet your project needs. Usage:
Pinyin.class.php source code:
function g($num) {
if ($num > 0 && $num < 160) {
return chr($num);
}
elseif ($num < -20319 || $num > -10247) {
return "";
} else {
for ($i = count($this->d) - 1; $i >= 0; $i--) {
if ($this->d[$i][1] <= $num)
break;
}
return $this->d[$i][0];
}
}
function c($str) {
$ret = "";
for ($i = 0; $i < strlen($str); $i ) {
$p = ord(substr($str, $i, 1));
if ($p > 160) {
$q = ord(substr($str, $i, 1));
$p = $p * 256 $q -65536;
}
$ret .= $this->g($p);
}
$ret = substr($ret, 0, 1);
return $ret;
}
function f($str) {
$ret = "";
for ($i = 0; $i < strlen($str); $i ) {
$p = ord(substr($str, $i, 1));
if ($p > 160) {
$q = ord(substr($str, $i, 1));
$p = $p * 256 $q -65536;
}
$ret .= $this->g($p);
}
return $ret;
}
